The company is a leading technical nonwoven business serving the international market with products for specialist military applications.
Nonwovens have grown in popularity as new and beneficial properties were developed into multi-layer composites fabrics. These fabrics are lighter in weight, significantly more breathable and superior in tear and breaking strength over conventional products. A good example is UHMWP (ultra-high molecular weight polyethylene) for ballistic applications.

of the antenna provides a sensitive omni output for this band. A decagonal cylindrical cavity inside the antenna allows switching, amplification and RF processing to be integrated into the antenna for a reduction in cable loss and weight. Alaris Antennas designs, manufactures and distributes antenna products for the global defence, homeland security and specialised antenna markets. While its clients are mostly international EW system houses, it also serves government organisations that use the products for military defence, security, VIP protection and general communication Q purposes.
